Does QuickBooks offer the option for my clients to click into their invoices and pay direct rather than a bank transfer.

Hi emma17, 

Currently the only payment methods we support are PayPal and GoCardless, other than this you would add bank details to the invoice so the customer can manually make payment via their bank.

Thanks

h @emma17 ,

You may explore Veem as another option. It supports QBO.
